Precision Digital offers three different light configurations in its line of Light / Horn devices. The first option is a factory ordered Light / Horn with a color of either red, green, yellow, blue, or white. The second option is a Light / Horn the user determines the light color (red, green, yellow, blue or white) by connecting the appropriate wire. The third option is a Light / Horn with red, yellow, and green layers the user can turn on independently. The light on the Light / Horn can be wired to flash (not available on PDA-LH5C) or stay steady on and the horn is rated at 85 dB. The light and horn can be controlled independently of each other via separate relays on the Precision Digital meter; and since the meter's relays can be reset in a variety of ways, there are several ways the Light / Horn can operate. For instance, the horn can be programmed to silence at any time via the Reset Button or F3 front panel button (on ProVu models), and light to turn off automatically when the alarm clears.
A typical way to use the PDA-LH is to program the meter so the horn can be silenced via the Reset Button at any time and the light to reset automatically after alarm clears:
|Relay||Connected to||Default Reset|
|1||Flashing Light(1)||Auto reset|
|2||Horn||Silence with Reset Button|
|3||User Device||As user desires|
|4||User Device||As user desires|
|1 Light can be wired to flash or stay steady on.|
The PDA-LH5C shows one of five possible colors at a time. A typical application might use the green light to indicate everything is OK and the red light to indicate high and low alarms:
|1||Low alarm||Red light||Auto|
|2||All OK||Green light||Auto|
|2||High alarm||Red light||Auto|
Indicate everything is OK with the green light, a High warning with the yellow light, and a High alarm with the red light. The Horn would also sound at both High warning and High alarms and can be manually reset at any time.
|1||All OK||Green light||Auto|
|2||High alarm||Red light||Auto|
